I've had these for a couple of years and haven't had any issues or white noise . FYI, the power con is designed to have the blue connector plugged in before you connect actual live power. Sequence for powering on should be: 1. Connect blue connector. 2. Connect live power to outlet Sequence for powering off: 1. Disconnect power from outlet 2. Disconnect blue connector. What do you have the gain set to? I typically run my gain on the HDM 45 at 15. Proper gain staging will reduce the hiss you hear. Are you using an external mixer or connecting straight from your mixer/controller to the speakers? I run my setup off an Allen and Heath Zed 10 FX. I have the Main Mix Level set to Unity, and use the PFL to set the Gain from my Rane One to where it bounces into the greens. Then adjust your sound level needed on the Channel Level. This guy here has a good tutorial on proper gain staging. kzfaq.info/get/bejne/gMWpgtmV0bO5cZs.html Also use the built in the DSP Presets for your room. Small room I typically change it to C1 for close listening, it cuts the highs. For deep long throws, I change the setting to F1 for Far listening, you will get more throw on the highs. Set the DSP and walk around the room to see if you like the sound and adjust from there. The L4 setting will get you more bass but you will reduce headroom. As you stated, subs do a better job since they are typically on the ground and you get additional bass from the boundary of the floor. Hope this helps.

Very clear cut review/information. You should do more product vids like this! Earned a sub.

Thanks for your video

I just bought ones today they sound good but at least one woofer needed for outdoors or large places

I own these and use them for larger events. These are hands down the best powered speakers I've ever used and I had many. They make sense even at smaller events because they are so light weight and easy to carry. I agree with you, you do need a subwoofer for most venues.

Hey I’ve had the rcf hdm45 for about 2 years now and they are one of the loudest top I ever had. However my previous tops was the JBL SRX835p and that you definitely won’t need a sub but being 85 lbs is the reason I sold it. As far as limiting on the rcf I’ve pushed mines really hard with no issues. The yellow is just a soft limiter. Rcf has so much protection built into that thing. If your in need of subs look into the Bose sub 2 for portability you’ll thank me later. 2 of those I think is equal to 1 rcf 8004 😊

I got the RCF 945a and they are a monster of speakers. The bass is there but I always set it up with subs. The reason is sound quality. I had the opportunity to dj next to other DJs that don't use subs and 95% of the time people prefer how my system sounds. So don't sacrifice spud quality just because you don't want to carry a subwoofer.

Would buy them again for your application

Also is there any RCF speaker that would work well In a 35 sq meter room without the need of a sub? I'm a bedroom DJ who plays mainly house & techno and I'll be throwing the occasional party with 20 people max. Thanks bud

Is RCF tt5a & Bassboss vs21-mk3 a good combination as for a top and bottom ? Or should I go with a tts 18-a mk2…

Bro that was a great purchase!. Does the white noise happens to your evs?. Could the yellow light be a warning and it might turn red when is definitely at its peak?

Hi, what are the main differences between this and the HDM 35 sound wise? Best wishes

what do you think about the rcf art 714 mkh4? I'm planning to buy two of these, they seem like a perfect price, one in my country costs €500

I never dj for most os 180 pip outdoors do you recommend this or its too harsh for close listening

I have rcf hdm 45 I have same problem hiss sound and ringing sound

I tested to the max where yellow light flickers and gives a rumbling sound not very pleasant thought it was blown after checking everything it’s just the speaker seems like the plastic cannot handle all the bass

Is the nx945 better than this one since its wood?

if you want an full range 2 way speaker with decend bass you need to buy an speaker with a wooden large body. But it will be heavier, you can't get a lot of bass with a light speaker, these are the laws of physics.

I heard you can’t go wrong with RCF, however I have the QSC K12.2 and I think it provides a significant amount of bass. They are a little lighter than the RCF model you have. Do you plan to stick with RCF or are you still trying out other speakers?

Better off probably getting a pair of 12 inch subwoofers and pairing them with your zlxs.

Ofc any speaker no metter how much they cost will be better with subwoofer 😅😂 this hdm i have them for 2-3 yrs don’t know month when bought😂 have stronger bass than famous 745 wich i was lookin for 😂 and becouse they are more clear sounding betwen those 745 sound more ruff in bass so they sound similar but hdm is harder on punchin ^^ but u can correct spunding with mixer or pressets 😂 btw it has 4inch coul in hf driver but lf driver is 3.5 ^^ cimpared to ur ev entry lvl speaker its like 2 times bigger and stronger 😂 not to make fun but its true… sound and feel wise it goes down to drivers ofc but allso depends on a loot different things… box is it wood or plastic, some plastic speaker sound like subwoofer but allso depends on parameters on pressets in AMP any AMP in speaker, crossower point etc etc and etc… if u wanna mind just mind deciwing sound from bass ur better than 745 but becouse hdm hase 400w more to spare 😂 u can make it sound like it couse of extra head room and get better bass, this speaker destroy in bass 745 not a loot but in my case 745 on boost doesnt hit harder than hdm45 on flat just… not on boost 😂 i was just playin on mixer 😂
